IncAAM 1.9
Summary presentation and
defaults
- Removed the
note column from fit$summary
and changed both existing plot subtitles to display
TR median instead of the TR threshold; the ogive plot no
longer labels the same estimate as Median A50.
- Simplified
fit$summary by removing p5,
p95, and n_posterior_draws; retained
CrI95_low and CrI95_high and the posterior SD.
The draw counts remain available in ogive metadata.
- Updated default female and male TR thresholds to
0.16 and 0.25, respectively. Users may
still override them with explicit arguments.
- Corrected the in-press methodological reference year to
2027 in the package documentation.
Changes to posterior
estimation
- Replaced the version 1.8 population estimate based on aggregates of
fish-level TR values with the hierarchical population median
TR from the population
log(c) intercept, using all
post-warmup posterior draws.
- Removed the last-observed-increment censoring from fish-level TR
draws and retained the posterior probability of crossing within the
original observed range (
TR_reached_prob) solely as a
diagnostic.
- Reported 95% Bayesian credible intervals (posterior 2.5th–97.5th
percentiles) for the hierarchical population estimates.
- Revised the group-level jerk estimate to the jerk of the
hierarchical reference curve, clearly distinguished from
fish-level diagnostic jerk summaries.
Analytical crossing ogive
- Replaced the logistic approximation based on averaged fish-level
probabilities with the analytical hierarchical posterior crossing ogive
from
log(c) population intercept and fish-level SD
posterior draws.
- Defined the estimated ogive A50 as the hierarchical population
median TR; the ogive A50 now has a 95% Bayesian credible interval.
- Added posterior-median crossing probabilities and both 90% and 95%
Bayesian credible limits to the ogive tables.
Increment selection
- Added
min_max_incnum to select fish based on their
original maximum observed increment (default
NULL, no restriction).
- Added
max_incnum_fit to cap the increment numbers used
in the growth-curve likelihood (default Inf, no cap).
- Preserved the original observed increment maximum for
threshold-reach diagnostics, even when only early increments are used in
the fit. The pre-existing
min_increments threshold is
evaluated on the capped fitting sequence.
Output and documentation
- Updated the group summary and ogive tables to identify hierarchical
estimands and posterior intervals; retained original result component
names.
- Reformatted the existing TR/Jerk density plot and crossing-ogive
plot. The ogive now uses 90% posterior credible shading rather than SE
bars; no additional plot types were introduced.
- Updated
README.md, function help, and package
description for version 1.9.
IncAAM 1.8
- Previous submitted version. Fish-level TR estimates were truncated
at each fish’s last observed increment; group summaries and a fitted
logistic crossing ogive were derived from aggregated fish-level
results.
